Abstract: Capture fisheries and aquaculture without feeding could not pollute the water bodies and reduce in some degree the growth of algae and control the eutrophication. Whilst aquaculture by feeding and fertilizing could increase the possibility of eutrophication. However, proper cage numbers and distribution, limited aquaculture species and density, increasing the quality of lowpollution aquafeed and proper feeding regime could reduce the negative impact of aquaculture on water bodies. Proper fisheries is one of the ways to utilize the resources of water, land and organisms of the Three Gorges Reservoir. It could not only increase the employment and income of the emigrants, but also improve the water environment. In order to utilize the water resources, properly it is urgent to make the fishery development plan and improve the fisheries management. It could result in the harmonizing of fisheries, environment protection, resettlement and other functions of the reservior.
